HelloI have the following text: xxxxxxxx = yyyyyyyyy. Spell checking is needed only for yyyyyyy part, so I added the rule:[rule name="1" id="2"] [pattern] [token regexp="yes"]^(.*?)=[/token] [/pattern] [disambig action="immunize"/][/rule]

but regexp, mentioned above is not working. It works fine in Java or Javascript and here I see no effect. When regexp changes, for example, to ^(.*?)abc - everything is ok if text is xxxxxxxxabc yyyyyyyyyyCould you suggest please?

In this case you'll have 3 tokens "xxxxxxxx", "=", "yyyyyyyy" so you have to build your rule to take to account 3 tokens not one. Something like:[pattern] [marker] [token][/token][/maker] [token]=[/token] [token][/token][/pattern]
